Custom symbol files

I'm confused as to how the custom symbol files option works.If I create my own symbol file (e.g. MySymbols.dat) as a copy of Wconsyms2004.dat and edit an entry, I get a warning message "Cannot open a symbol file for write" after clicking OK in the Symbol dialog box, but any edited symbols are shown as I amended them in the list box in the Select Symbol dialog box, and are applied to courses set while that instance of Condes is running.

If I save the event file and exit Condes, when I next run Condes with that event file, the symbols revert to the standard set, even though the symbol file is shown as MySymbols.dat in the Folder Settings tab of the Standard Settings dialog box.

If I then try to select MySymbols.dat by clicking on "Use my own symbool file Select existing file...", I get the message "MySymbols.dat This file is set to read-only. Try again with a different name."
